What does a plasmid do in the process of creating recombinant DNA?

plasmids or vectors are responsible for introduction of a foreign gene into an organism so the answer is D

it relatively is a DNA molecule that has been "recombined". What that refers to is the two deleting slightly of DNA that would usually be latest, or including a clean element of DNA that frequently does not be latest. Examples: some retroviruses artwork by utilising putting their DNA into the host DNA. They try this by utilising sporting alongside the enzymes mandatory. as quickly as the viral DNA inserts into the host, the recent DNA is recombinant. interior the lab, biochemist and molecular biologists use enzymes to control DNA. as an occasion, scientists can positioned genes for mammal proteins into bacteria, so the bacteria produce the mammalian protein. The viral DNA with teh mammalian gene is "recombinant DNA". a particular occasion is engineering bacteria to make human strengthen hormone. ultimately, mice is additionally altered interior the lab to make, as an occasion, human proteins. The human DNA is presented into the mouse DNA. This produces a "recombinant" mouse DNA.

D) Transfers a new gene into a bacterial cell

this occurs during conjugation of two bacteria. there is a sex pilus that connects the two bacteria and the plasmid travels through it from one bacteria to the other
